Good news is the pro cards have a 10 year guarantee if you can ever manage to get then to give you an RMA number

Also bought five from Amazon when they were £20 ish.

1 was dead on arrival but the other four are still working.

If you bought from Amazon, maybe quicker to get a refund if you contacted them first.

These should be fine to use in most devices including the Pi 3, obviously these will probably be formatted as ExFAT rather than FAT32. So will need to be formatted correctly but other than that it should be alright.

Also if MMLOYAL stops working VC5 is also a valid discount code for 5% off as well.
